Explain why a change, incident or session went as it did, separating proven causes from coincidence. Use when: asked for a postmortem, retro or root-cause write-up.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Postmortem Answer an explicit retrospective causal question about a completed or stopped goal, session, change or incident from its actual intent, outcome and judgment evidence. Neighbours: how a plan not yet run could fail is [Premortem](../premortem/SKILL.md); whether a finished change meets acceptance is [Validate](../validate/SKILL.md). ## First check: correlation or cause? Treat every causal statement as a hypothesis, including the one the caller arrives with. Promoting a claim from correlation to cause requires all three: - a stated mechanism: the specific path by which the condition produced the outcome, in terms a reader could check against the subject; - discriminating evidence: an observation that the mechanism predicts and at least one plausible alternative does not; - a counterfactual test: what should have differed if the claim were false, with cited evidence showing it did differ. Post-hoc fix attribution, "we changed X and the failure stopped, therefore X was the cause", satisfies none of these alone: the symptom may be intermittent, or the recovery and the change may share an unobserved cause. Keep such claims …

How to install
mdr add boshu2/agentops/postmortem@sha256:93ef2dcbc1f2f811The line at the top of this page pins the label git:20261031.73cbeae, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
